What sort of tuning does that Daewoo have, John, is it twiddly wheels or knobs or on-screen tuning via the remote?

I'm wondering if you are tuned to an 'image' of the signal rather than the actual signal. Try tuning completely off the signal you are currently tuned to and keep going for some way first higher than and then lower than the signal you know about.

According to my ZX81 manual which is conveniently to hand, the signal output from the ZX81 should be on UHF channel 36. However your TV is tuned, it should give you some indication of where in the channel range you are currently tuned to.
